Repair
A repair constitutes something done internally to the radio that would bring it back to its original
condition. Items not considered as repairs are those in which an action is performed on a radio
which does not require the outer casing of the radio to be opened in a manner which exposes the
internal electrical circuits of the radio.
Repairs of Motorola ATEX/IECEx certified intrinsically safe radios must be carried out ONLY
by Motorola I.S. trained personnel, who are aware of the special parts required and the
procedures necessary to maintain the ATEX/IECEx conformance of the product. The
Motorola internal service centres undergo regular training and receive a Motorola internal
certification that enables them to conduct ATEX repairs.

•
If any of the items below are observed, the intrinsic safety of the unit may be impaired and
the customer must be informed about this. Text proposal:

2. .....
...
These modifications are not authorized by Motorola and deviate from the approved design.
The modifications may impair the intrinsic safety of the units and as such may cause a higher

Contact the Motorola service organization (Georg Fröhlich) or the ATEX representaive (Fritz
Bollmann) for further assistance regarding repairs and service of ATEX/IECEx certified
Motorola equipment.
Service personnel doing ATEX repairs have to have a mandatory annual ATEX/IECEx
awareness training.
The participation in the ATEX/IECEx awareness training plus a detailed product training
certifies the person to conduct ATEX/IECEx repairs.
The training records have to be kept for at least 10 Years.
For every ATEX/IECEx repair at the minimum the service centre must record: Customer
information, date of repair, serial number, date code and model number of the unit that
was repaired, technician's name and ATEX training date as well as repair
information/parts replaced. These records have to be kept under record retention for at
least 10 Years after the repair was conducted.
If the radio has an IP6x protection, a vacuum leak test has to be conducted after the radio
is assembled. A confirmation that the leak test was conducted has to added to the repair
records.
It is essential that only original Motorola spare parts specifically listed for the particular
unit can be used for repair. Any other replacement parts are not allowed and may impair
the intrinsic safety of the unit.
